摘要/Abstract

摘要： 比较银介电常数三种色散模型对光学Tamm态的影响，根据三种色散模型的复折射率随波长的变化研究银-光子晶体-银结构TE波和TM波的光学Tamm 态随入射角、银层厚度及周期数的变化.得出：三种色散模型下银-光子晶体-银结构中都会出现两个光学Tamm 态（OTS1和OTS2）.三种色散模型下的光学Tamm 态的波长随入射角、银层厚度及周期数的变化规律一致.但是光学Tamm 态的透射峰值随入射角、银层厚度及周期数的变化规律不一致.Drude-Lorentz模型和Lorentz模型能够描述银的特征，而Drude模型不能.

Abstract: To investigate metal dielectric constant influence on optical Tamm state, complex refractive index in three dispersion models is studied. TE wave and TM wave of optical Tamm state with different incident angle and silver layer thickness and cycles number are studied in silver-photonic crystal-silver structure. Two optical Tamm state appeare (OTS1 and OTS2). In three dispersion models wavelength of optical Tamm state changing with incident angle and silver layer thickness and cycles number are similar. Transmission peak of optical Tamm state changing with incident angle and silver layer thickness and cycles number are different. Drude-Lorentz model and Lorentz model can describe characteristics of silver, but the Drude model can't.

Key words: photonic crystal, optical Tamm state, Drude-Lorentz model, Lorentz model, Drude model
